WOCE A10: Ocean Carbon Chemistry Measurements from the South Atlantic, 1992-1993

Discrete chemical and physical oceanographic measurements collected from the R/V METEOR in the South Atlantic Ocean during December 1992 and January 1993. The data includes partial pressure of carbon dioxide, dissolved inorganic carbon, pH, alkalinity, temperature, salinity, and trace gases. It was collected by researchers from Universitat Kiel as part of the World Ocean Circulation Experiment (WOCE) Hydrographic Program.

Use Cases

• Modeling ocean carbon sequestration based on partial pressure of carbon dioxide and dissolved inorganic carbon measurements.
• Analyzing ocean acidification trends based on pH and alkalinity data.
• Studying deep-water formation and circulation using chlorofluorocarbon (CFC) tracer data.
• Calibrating satellite-derived sea surface temperature and salinity products with in-situ bottle and CTD measurements.

Strengths

• Data collection is part of the major, internationally coordinated World Ocean Circulation Experiment (WOCE).
• Includes over 20 distinct chemical and physical variables, such as delta carbon-14 and tritium, for multi-parameter analysis.
• Covers a specific, focused cruise track (06MT22_5/WOCE_A10) in the South Atlantic Ocean over a continuous 36-day period.

Limitations

• Last updated 1993-01-31; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
